How to Fix a Spring in a Roll-Up Window Shade

Save

Roller shades provide privacy at night and keep out the sun during the day. With a slight tug at the bottom, you can raise or lower the shade with ease. Roller shades operate on a hollow tube-like roller with a spring inside. When you pull the shade down, it puts more tension on the spring. The tension is released when you raise the shade. If you are having trouble operating the shade, you can buy another roller tube or a new shade, but those are costly. Instead, try a few simple fixes.

Things You'll Need

  • Vacuum
  • Lubricating oil

Too Loose

Determine the source of the shade's problem. A shade that snaps up and takes more strength to pull down usually has a spring that's too tight. If your shade won’t stay up, proceed to Step 2. For a shade that doesn't stay down, skip to the next section.

Remove the roller shade from the brackets. One end lifts upward off the bracket; the other end pulls free from the bracket.

Unroll the shade material about 4 to 6 inches. If you have an extremely loose shade, unroll the shade material to the halfway point.

Roll the shade material back onto the roller with your hands.

Install the roller shade back in the window brackets.

Pull the shade down and see if the shade works. If it doesn’t, repeat the process.

Adjusting Uncoiled Spring

Remove the shade from the brackets. One end lifts upward off the bracket; the other end pulls free from the bracket.

Examine the two ends of the roller. Find the end with the flat pin.

Vacuum away dust and debris from the pawl, a small arm mechanism that engages the ratchet teeth. You can also use an air compressor or toothpick to clear away dust, debris and cobwebs.

Spray lubricating oil onto the pawl.

Hang the window shade in place. Pull it down to see if it works better. If you are still having the problem, repeat Steps 1 through 5 until your shade works.

Tighten Spring Action

Lower the roller shade as far as it will go. Remove the shade from the brackets.

Roll the shade up by hand to the halfway mark.

Install the roller shade in the brackets.

Pull the shade down and then try to raise the roller shade. Repeat if necessary.
